stun FOR SHIRT-BOSOMS.

SPECIFICATION forming part of Letters Patent No;724,591 dated April 7, 1903.

Application filed July 81,1902.

To all whom it may concern:

Be'it known that 1, JAMES W. LAWSON, a citizen of the United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Studs for Shirt- Bosoms, of which the following is a specification, reference being had therein to the accompanying drawings.

Like'letters indicate like parts.

Figure 1 is a side elevation of myinvention. Fig. 2 is a bottom plan View of the same.

My invention relates to studs for shirtbosoms; and it consists of the novel construction and combination of the several parts, as hereinafter described, and specifically set forth in the claims.

In the drawings, A represents the head or ornamental front of my improved shirt-stud. The shank B is fastened to the head A on the under side thereof, at the center, preferably by solder, and is of any proper diameter, as shown in Fig. 1. It is provided with an integral circumferential ridge or'enlargement (designated as a) and may be made in any suitable manner. The portion of the shank B beyond the circumferential ridge to and indicated as b in Fig. 1 is of a reduced tapering diameter, and the remainder of the wire continues of the smallest diameter except at the bend or how, (marked 0,) where it is flattened and thinned. The portion 17 is bent and curved a quarter-turn, as shown at din Fig. 2. Then the wire is straight for a certain length, as seen at 6. Then it is bent into a half-circle, as at c, (where it is also flattened). Then it extends straight and parallel with the portion 6, as illustrated at f. Then it is bent and curved almost a quarter-turn, as shown at g, and there comes in contact with the curve I), and thence it extends straight, as at h, in a line parallel to the radius of said head A in the same direction, but to a length equal to the loop formed by the parts e, c, f, and g.

To insert this improved stud in the shirtbosom, the outer end of the straight portion h is thrust through the eyelet-hole of the shirtbosom on the front, and the wire is pushed until the inner edge of the-bow c, at the center thereof, abuts the open edge of said eye- Serial No. 117,866. (No model.)

until the cloth lies between the ridge a and the under side of the head A. The ridge a as the stud is drawn expands the eyelet-hole of the starched linen shirt-bosom sufficiently to enable it to pass through to the rear of the bosom, and then the resilience of the stiff cloth causes the eyelet-hole to close in snugly against the shank B, and thus the ornamental front or head A of the stud is kept in position and has a snug contact-with the front of the shirt-bosom.

The wire constituting the loop above described should have a sufficient resilience to allow the shirt-bosom to pass between the parts I) and g when said wire is pushed with a slight force. The flattening of the how 0 gives a resilience to the loop, enabling a slight movement of the tongue portion h in the plane of the shank B. These two resilient.

movements insure the proper contact and pressure of the parts 6, o, f, g, and h against the inner surface of the shirt-bosom. It is obvious, however, that the circumferential ridge a may be dispensed with and also that the bow 0 need not be flattened, but may remain cylindrical in cross-section, and yet the stud will be useful and efficient, the essential feature of my said invention being the elongation of the shank of the stud into a wire (preferably reduced in diameter) and bent into a loop, closed at its outer end and lightly touching at its inner end the curved portion 19 and terminating with an integral pin-shaped tongue.

This stud, when once the end of the tongue h is inserted in the eyelet-hole of the shirtbosoin, is easily and rapidly broughtinto wearing position bya push, atwist, and apull and is as easily removed and detached by following the same movements in a reverse order.

The comparatively long area of contactot the wire bent and shaped as described against the under side of the'shirt-bosom prevents any tipping of the stud or other undesirable or improper position of it in relation to the shirt-bosom. This loop of the wire somewhat resembles the well-known spiral twist of the shank of a shirt-stud, but difiers therefrom because it is fiat, and therefore every part of the loop, as well as the tongue, assists by the contact and pressure thereof in holding and maintaining the stud in proper wearing posifront or head and a shank terminating in an elongated integral wire having a quarter-turn, two straight portions parallel with each other and connected by a semicircular bow, a straight tongue portion extending in a line parallel with said two straight portions but in an opposite direction and midway between them and connected with one of them by a quarter-turn, substantially as shown.

2. The improved stud for shirt-bosoms herein described, consisting of an ornamental head and a shank having a circumferential ridge on a line close to and parallel with the back of said head said shank being curved and extending in an integral elongated wire of reduced diameter, which is shaped into a flat loop closed at the outer end and at the inner end lightly touching the curve of said shank and terminating in a straight tongue, substantially as specified.

3. The improved stud for shirt-bosoms herein described, consisting of an ornamental head and a shank curved and extendinginto an integral elongated wire, the latter bent into a fiat loop closed and flattened atits outer end and lightly touching at its inner end the bend of the shank and terminating in a straight tongue, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES W. LAWSON.
